"One of the most unique things about
this job is that we are using a structural
steel system that utilizes what we call SIN
beams," says Anderson. "It's a lighter beam
that can be manufactured to produce the
same stiffness and performance qualities,
but there is a tremendous weight savings."
Steelcon describes the SIN beam as a new
product that will change the industry standard for conventional steel construction. It
consists of a corrugated web, built from steel
coils and thin steel flanges constructed from
steel flat bars. The result is a lightweight
steel member with increased load capacity.
Its use in construction can reduce the
weight of a structure by up to 30 percent.
Using lightweight materials and robot-automated manufacturing, the SIN beam provides significant cost savings in materials
for all types of steel construction projects.
"When you propose using a structural
system that may be unfamiliar to others,
there is a bit of resistance or apprehension
to overcome," Anderson says. "This is the
first time this beam is being used by Ellis-
Don. It's a bit of innovation that we brought
to the job."
EllisDon has spent more than a year
pursuing the Seneca King project. Requests
for proposals started in 2014. As many as a
hundred team members were involved in
putting together the project, Anderson says.
As with any project this size, it has had its
challenges. EllisDon had to adhere to strict
performance and specification guidelines
set out in the contract, which required a
significant amount of coordination. From
strict compliance and design components to
attaining municipal permits and approvals
with minimal lead times, the project has
seen its share of ups and downs - especially
when the weather wasn't compliant.
"We have been challenged by wet weather and the resulting adverse site conditions
in recent months," Anderson says. "But the
site team is working well to address any risk
to the project schedule by working closely
with the subtrades to implement a strategy
whereby early access is provided to work
areas out of the original planned sequence."
EllisDon is known for its commitment to
the environment. In 2016, the company
partnered with seven other influential
companies in Canada to develop an industry-led action plan in support of Canada's
national and international climate change
commitments. The Carbon Impact Initiative,
as it has become known, is bringing together
environmentally conscious industry champions and government leaders in hopes of
creating strategies and establishing low-carbon built environments in Canada.
Seneca College's King Campus will be an
example of a green initiative. The project
calls for LEED Gold standards in the Canada
Green Building Council's Leadership in
Energy and Environmental Design rating
system. "It's a sustainable design approach
that focuses on locally sourced materials,
recycled contents and measures that reduce
carbon impact," Anderson says. "In this day
and age, everybody is pushing for green.
Every project seems to be moving towards
some sort of LEED certification."
